Sorbaria plant named ‘Bococot’

ABSTRACT

A new cultivar of Sorbaria sorbifolia plant named ‘Bococot’ that is characterized by its compact, dense and consistent plant habit, its floriferous blooming habit in summer, its foliage that is deep pink-red in color, and its fruits that are greyed-red in color.

Botanical classification: Sorbaria sorbifolia.

Variety denomination: ‘Bococot’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sorbariasorbifolia and will be referred to hereafter by its cultivar name,‘Bococot’. ‘Bococot’ is a new cultivar of false spirea, a shrub grownfor use as a landscape plant.

The new Sorbaria arose from a breeding program conducted by the Inventorat a nursery in Boskoop, The Netherlands. The objective of the breedingprogram was to develop new Sorbaria cultivars with dense and compactplant habits, new foliage colors, and good flowering properties.

The new Sorbaria originated by open pollination in June of 2014 ofSorbaria sorbifolia ‘Sem’ (U.S. Plant Pat. No. 16,336) as the femaleparent. There were numerous plants of unnamed and unpatented plants ofSorbaria sorbifolia planted in the area. The male parent is thereforeunknown. ‘Bococot’ was selected as a single unique plant from theresulting seedlings in 2016 (seedling reference no. 1601-01) with finalselection for introduction made in 2019 after a propagation trial.

Asexual propagation of the new cultivar was first accomplished by theInventor using stem cuttings in summer of 2018 in Boskoop, TheNetherlands. Asexual propagation by stem cuttings has determined thatthe characteristics of ‘Bococot’ are stable and reproduced true to typein successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent thecharacteristics of the new cultivar. These attributes in combinationdistinguish ‘Bococot’ as a unique cultivar of Sorbaria.

-   -   1. ‘Bococot’ exhibits a compact, dense and consistent plant        habit.    -   2. ‘Bococot’ exhibits a floriferous blooming habit in summer.    -   3. ‘Bococot’ exhibits young foliage that is deep pink-red in        color.    -   4. ‘Bococot’ exhibits fruits that are greyed-red in color.

The female parent plant of ‘Bococot’, ‘Sem’ differs from ‘Bococot’ inhaving a shorter plant height, young foliage that is lighter in colorand more grey-orange in color, a less floriferous blooming habit, fruitthat is more brown in color, and a more vigorous spreading habit.‘Bococot’ can be compared to the Sorbaria sorbifolia cultivar ‘Levgreen’(U.S. Plant Pat. No. 31,202). ‘Levgreen’ differs from ‘Bococot’ inhaving a smaller plant size, mature foliage that is bright green andtinged with bronze in summer, and a very sparse blooming habit.
